Description: The nuclear pore complex (NPC) is a 125 MDa nuclear envelope complex that mediates nucleocytoplasmic shuttling of RNA and protein. NPC is comprised of more than 30 different proteins, including Ran/TC4, importins, and exportins . Exportin-1(hCRM1/XPO1) is the widely expressed human homologue of the yeast CRM1 protein, which functions in the maintenance of chromatin structure and nuclear export. Exportin-1 has an N-terminal CRIME domain that is homologous to yeast CRM1 and importin-beta. Intracellular localization of Exportin-1 shows association with the NPC and overexpression of Exportin-1 in Xenopus oocytes stimulates Rev and U snRNA export from the nucleus. Exportin-1 also binds other nuclear transport related proteins, such as RanGTP, snurportin-1, and the nucleoporins CAN/Nup214 and Nup50. Overexpression of CAN leads to sequestration of Exportin-1 in the nucleoplasm, which inhibits cell growth and induces apoptosis. In addition, Exportin-1 may export specific proteins, such as Rev and PKI, via binding to a leucine-rich nuclear export signal (NES). Thus, Exportin-1 is an important protein and RNA nuclear export receptor, which may be required for normal cell growth and survival. This antibody is routinely tested by western blot analysis.
